QUESTION 23Refer to the exhibit. The vrf MAINT has been provisioned and used by the Service Provider management network. The engineer discovers that syslog messages are not being received on the syslog server. IP reachability has been validated using ping. Which issue in the configuration must be corrected?

A. logging on must include the vrf MAINT keyword.B. logging host must include the vrf MAINT keyword.C. The logging facility must be configured for syslog processing.D. The route targets that are configured do not match the route distinguisher.

QUESTION 25An R1 router requires an equal load balancing to reach the prefix 192.168.0.0/16 over two exit points: through R2 and R3 routers. Which two options must be configured on the R1 router to achieve this goal? (Choose two.)

A. The BGP maximum path feature must be configured on R1.B. The BGP PIC core must be enabled on R1C. Weight, local-pref, MED, as-path length, origin, and the BGP next-hop IGP cost must be the same for the R2 and R3 IBGP updates to R1.D. The BGP Link Bandwidth feature must be applied on R1.E. BGP extended community exchange must be enabled between IBGP neighbors.

Answer: ACExplanation:BGP link-bandwidth is for unequal-cost routes.

QUESTION 26A company is deciding between an HVR and SVR solution in order to finalize a virtualization project proposal. Which is an advantage of a HVR solution versus a SVR solution?

Answer: ABEExplanation: Asynchronous response mode is an HDLC addition[1] for use over full-duplex links. While retaining the primary/secondary distinction, it allows the secondary to transmit at any time. Asynchronous balanced mode added the concept of a combined terminal which can act as both a primary and a secondary. There are some subtleties about this mode of operation; while many features of the protocol do not care whether they are in a command or response frame, some do, and the address field of a received frame must be examined to determine whether it contains a command (the address received is ours) or a response (the address received is that of the other terminal).

QUESTION 30Refer to the exhibit. In the short-pipe QoS mode, this customer has QoS control for which two links? (Choose two.)

QUESTION 32A network engineer is responsible for implementing a solution with Cisco IOS XR Software that insures continuous forwarding during a control plane failure. Which two technologies should the engineer consider? (Choose two.)

QUESTION 33What are three main characteristics of mLDP that differ from RSVP-TE? (Choose three.)

A. The LSPs are built from tailend to headend.B. The LSPs are built from headend to tailend.C. It supports only P2MP LSPs.D. It supports both P2MP and MP2MP LSPs.E. Signaling is periodic.F. No periodic signaling is performed.

QUESTION 34Which are the two purposes of the MPLS label value 1? (Choose two.)

A. it is used for MPLS OAM packets.B. it indicates an implicit null label.C. it is used for VPNv6 packets.D. it is used to carry the QoS value in the label stack.E. it indicates an explicit null label.F. it indicates a router alert label.

Answer: AFExplanation:A value of 1 represents the "Router Alert Label". When a received packet contains this label value at the top of the label stack, it is delivered to a local software module for processing. The actual packet forwarding is determined by the label beneath it in the stack. However, if the packet is forwarded further, the Router Alert Label should be pushed back onto the label stack before forwarding. The use of this label is analogous to the use of the "Router Alert Option" in IP packets (for example, ping with record route option)http://www.cisco.com/c/en/us/support/docs/multiprotocol-label-switching-mpls/mpls/4649-mpls-faq-4649.html6

QUESTION 35Refer the exhibit. Two Autonomous Systems are enabled to support multicast. An engineer wants to set up configuration so that a multicast client at AS 100 can receive multicast traffic from the M-Server at AS 200. However, the RP announcements must be limited within each autonomous system site. Which Cisco IOS configuration achieves this goal?

A. On both ASBRs Eth0/0 and the no ip pim sparse-mode command.B. On both ASBRs add the ip pim send-rp-discovery scope 1 command.C. On both RPs add the ip pim send-rp-discovery scope 2 command.D. On both ASBRs Eth0/0 and the ip pim bsr-border command.E. On both ASBRs Eth0/0 and the ip pim dense-mode command.F. On both RPs add the ip pim bsr-border command.

A. Clusters are used in confederation schemes to avoid loops.B. BGP network can have a confederation within a route reflector area.C. An internal BGP network cannot have a route reflector within a confederation.D. An internal BGP network can have a route reflector within a confederation.E. Clusters are used in route reflector schemes to avoid loops.F. BGP network cannot have a confederation within a route reflector area.
